Remember the old Fillmore Real Estate office at 486 Fifth Avenue in Park Slope? You know, the one between 11th and 12th Streets that closed down along with a couple of others as the real estate market started to, uh, sink. Well, the place is coming back to a life, per a tip from a very kind GL reader. We’d been by there yesterday and it was still the empty Fillmore office. Today? There’s paper covering the window and a building permit issued two days ago showing that it’s being converted to a restaurant/drinking establishment. There are no clues on the permit as to what kind of place it will be and we couldn’t find any pending liquor license application. If anyone knows, do let us know in the comments section. Oh, wait, we know…it’s going to be a bar called Apocalypse Now that play The Doors’ The End over and over and over and over.
